UK Detects Invasive Mosquitoes That Carry Diseases
The UK has detected two species of disease-carrying mosquitoes, Aedes aegypti and Aedes albopictus, for the first time. These invasive species, known as tiger and Egyptian mosquitoes, pose a risk of transmitting diseases like yellow fever and dengue.
In August 2024, tiger mosquitoes were spotted at a motorway service station in Kent. A year earlier, in September 2023, Egyptian mosquito eggs were found near London's Heathrow Airport. The UK Health Security Agency (UKHSA) runs the Mosquito Recording Scheme (MRS) to monitor and detect such unusual species. Between 2005 and 2021, only native UK mosquitoes were reported to the MRS, totalling 286 cases.
Rising temperatures and milder winters may facilitate the northward spread of these invasive species. Historically, they were confined to subtropical and tropical regions, but the tiger mosquito has now established populations across parts of southern and central Europe. Each detection in the UK has triggered enhanced local surveillance and control measures.
The UKHSA and the Centre for Climate and Health Security have published these findings in a peer-reviewed study. While no specific details are available about the next planned actions to prevent the spread of these mosquitoes near London, authorities are closely monitoring the situation to mitigate potential disease risks.
